A Brayton cycle using air receives the air into the compressor at 100 kPa and 290 K. The air has a mass flow rate of 50 kg/s. The air enters the turbine at 1250 K. Consider the air to have constant specific heats. Plot the ratio of the compressor power to the turbine power, the net power produced, and the thermal efficiency of the cycle for compressor outlet pressures ranging between 400 kPa and 1500 kPa for (a) an isentropic compressor and turbine, and (b) a turbine with an isentropic efficiency of 0.80 and a compressor with an isentropic efficiency of 0.75.
